Ink Doctor Blade Overview

In offset printing, the ink doctor blade controls the complex process of ink transfer, involving the ink, the printing plate, and the paper. In gravure printing, the ink doctor blade is a relatively simple mechanical operation, but it possesses its own unique characteristics. The ink doctor blade must be wear-resistant and highly efficient to ensure high-quality printing, and it must meet the durable and high-speed requirements of modern gravure printing. An ink doctor blade is a thin blade on a printing press used to scrape away excess ink from the surface of the printing cylinder; it comes in both metal and non-metal types. Removing ink from non-patterned areas is a crucial aspect of each printing process.
